With an urgent need for pitching, the Cubs took measures toward securing future options Monday night by adding pitchers Adbert Alzolay and Oscar De La Cruz to their 40-man roster.

They also added infielder David Bote, who batted .333 with four home runs, 14 RBIs and a .395 on-base percentage for Mesa in the Arizona Fall League.

Alzolay was second and De La Cruz sixth in Baseball America’s ranking of the Cubs’ best prospects.

Alzolay, 22, received plenty of interest in the weeks leading up to the trade deadline. He went 7-4 with a 2.99 ERA in 22 starts for Class A Myrtle Beach and Double-A Tennessee, striking out 108 in 114 1/3 innings, then struck out 13 in 11 2/3 innings for Mesa in the AFL.

De La Cruz, 22, was 4-3 with a 3.34 ERA in 13 games for Myrtle Beach and the Cubs’ rookie affiliate in Arizona. He’s 20-10 with a 2.83 ERA and 248 strikeouts in 2542/3 innings over five minor-league seasons. He was scratched from the AFL because of a pectoral muscle injury.

The Cubs announced that outfielder Jacob Hannemann cleared waivers and was outrighted to Triple-A Iowa.

The moves put the roster at 36, leaving room for a free-agent signing, a waiver claim or a Rule 5 selection.

Hannemann, reclaimed last month from the Mariners, for whom he batted .150 in 20 at-bats, and pitcher Jake Stinnett are eligible for the Rule 5 draft on Dec. 14. Stinnett, 25, allowed only 15 hits while striking out 27 in 222/3 innings at three minor-league levels and struck out 14 in 10 innings for Mesa in the AFL.

The next major deadline will be Dec. 1, when teams must tender contracts to all remaining unsigned players on their 40-man roster.

The Cubs will have difficult choices with relievers Hector Rondon and Justin Grimm, both of whom are eligible for arbitration.
